A 45 foot ladders leaning up against a building. The base of the latter is 20 feet away from the building. What is the angle of

Tatiana [17]

Answer:

The angle of elevation to the top of the building is 63.61 degrees

Step-by-step explanation:

Here, we want to calculate angle of elevation to the top of the building.

For this, we need a triangle

Please check for this in the attachment.

From the diagram, we are to calculate the angle theta.

To do this, we use trigonometric identities.

Looking at what we have, we have the hypotenuse and the adjacent.

So the trigonometric identity to use is the cosine

Mathematically Cosine theta = adjacent/hypotenuse

Thus, Cos theta = 20/45

Cos theta = 0.444444444444444

Theta = Arc cos(0.444444444444444)

Theta = 63.61 degrees

To divide the sector into two congruent sectors we can use the _________________ construction. A) angle bisector B) copy and ang

12345 [234]

Answer:

Option A) angle bisector

Step-by-step explanation:

Angle Bisector:

An angle bisector is a line that divides an angle into two equal parts.
The angle bisector divide the angle in two equal parts.
An angle bisector is equidistant from the sides of the angle when measured along a segment perpendicular to the sides of the angle.
It cuts the angle into half.
Thus, a sector can be divided into two equal sectors by drawing an angle bisector.

To divide the sector into two congruent sectors we can use the angle bisector construction.

Thus, the correct answer is

Option A) angle bisector

PLEASE ANSWER ASAP What does it mean for a scatter plot to have a negative trend?

mestny [16]

Answer:

D: None of these are true

Explanation:

If the points on the scatter plot seem to form a line that slants down from left to right, there is a negative relationship or negative correlation between the variables. If the points on the scatter plot seem to be scattered randomly, there is no relationship or no correlation between the variables
